Well we don't support that syntax at this moment. If you are saying
that we could add support for such syntax.. it does seem a good
idea, but in that case we would need to modify a few rules of the
grammar (like adding a const_expr production, and allow
static_scalar derive it, etc..).
Right, that's what I had in mind. That doesn't seem to break
anything and allows also a little more freedom. let's see if anyone
objects.
I tried implementing this and it seems much more complicated than what
I though. I modified the static_scalar rule of the grammar and I got
hundreds of reduce/reduce and shift/reduce ambiguities. Ignoring the
warnings, well.. didn't work (the parser then couldn't process the
run-tests.php script).

P.S.: I already spoted a few more places where we can produce better
byte-code (including more simple constant folding).. but one thing at
a time :)
